How can I scale my fluid simulation so that the droplets aren't so large?
After Ray M rewrote my Question headline, the changed wording caused the site search engine to find a similar -- duplicate, actually -- question (Smaller drops in fluid simulation) and this led me to the answer:

Higher resolution will make droplets smaller.

I have therefore done a 2-hour Bake at resolution 200, and am awaiting a multi-hour render to see the result.  I think I'm learning that realistic Fluid Sim is very, very expensive in CPU time. [btw thanks Ray :-)]
